Until, when death comes to one of them, he says: "O my Lord! send me back (to life)―
In order that I may work righteousness in the things I neglected. By no means! it is but a word he says Before them is a Partition till the Day they are raised up.
[Qur'aan, Surah Mumi'noon 23, Verses 99-100]
Why should we wait until that time brothers and sisters?
Let's all start doing righteous things today InshaAllaah, so we have no regrets on our deathbed.
